Typically, the knee cap (patella) fits directly into a groove in the thigh bone (femur). When the leg flexes and straightens, the patella should stay within this groove in the thigh bone. Patellar luxation signifies that the knee cap does not slide up and down within the grove. There are various explanations why such things happen, such as the malformation of the groove. Luxation could happen very rarely, or perhaps may occur continually. The actual knee cap could possibly pop back into the groove by itself, or maybe the vet might need to force it back into position. An individual's yorkie will likely be unable to walk in the event the patella is actually out of position.

Portosystemic Shunt (Liver Shunt)

A portosystemic shunt (PSS) is a condition in which there is abnormal blood flow thru the liver. Blood flows from the digestive tract to the liver and then thru the liver. Once the blood flows thru liver it is returned back to the heart. One of the major functions of the liver is to remove toxins from the blood. Many of these toxins are a result of the digestion of protein. High levels of ammonia in the blood stream are typical in yorkies with a portstemic shunt. The reason the ammonia levels are high is because, When there is a portosystemic shunt the blood or a portion of the blood by-passes the liver and is then returned to the heart.The blood or portion of blood can by-pass the liver either by a blood vessel that goes arround the liver or by a blood vessel that carries blood that passes thru the liver but doesn't allow blood to be processed by the liver. Many of the symtoms of a portostemic shunt are neurological. Portosystemic shunts may be acquired secondary to another disease, or they may be congenital - that is the yorkshire terrier is born with a shunt. A congenital shunt typically happens when a solitary abnormal blood vessel which is a remnant associated with regular embryonic growth. If the shunt passes arround the liver the shunt is defined as extra-hepatic. If the shunt passes thru the liver the shunt is defined as intra-hepatic.

Most yorkshire terriers having congenital portosystemic shunts display health-related indications prior to six months of age. When symptoms tend to be subtle, the situation might not be identified till much later.
